Here! iPhone 6 Plus Restart infinitely With Hardware Solution


Why my iPhone 6 Plus restarts infinitely? When press the iPhone power button, the white Apple logo appears normally, but then it turns off, the iPhone 6 Plus always restarts when the white Apple logo appears.  We tried several software solutions, but all is not working. Now we will try hardware solution to fix this problem.


As we know, the iPhone CPU, iPhone Nand flash, iPhone logic eerpom IC, iPhone baseband all will cause the iPhone restart failure. So, we need to check them step-by-step. 

Firstly, check the working condition for these chips.

Measuring the grounding resistance value and power supply for the iPhone CPU, both measured value are normal. Next measuring the working condition of the iPhone Nand flash, it's also normal. When measured the iPhone eeprom IC, we found the bus (AP_TO_EEPROM_I2C) connected to the iPhone logic eeprom IC and the iPhone CPU has some problem, the grounding resistance value for one of clock bus is more than 600, but the normal data should be around 400, seems there is a disconnection or the pin of the iPhone CPU is empty-welded.


Because there are only 1 bus has the problem, so we choose to dig the iPhone CPU, so that we can solder the jumper wire. According to check the iPhone schematic diagram via ZXW Dongle, so we can confirm the areas of excavation. Put iPhone motherboard under the Stereo Zoom Microscope, install the new blade to the handle, and then we can start to dig the iPhone CPU.


Dig through the iPhone CPU upper layer , then start to dig the iPhone CPU lower layer, now is the most critical position，we need to be very careful.


Dig off the first layer of ground circuit wire and leak out the circuit wire of the second layer of signal.


Carefully dig out the circuit wire, apply the green UV oil on the extra area, and connect another side to the AP_TO_EEPROM_I2C_SCL pull-up resistor.


Use digital multimeter to measure it again, the grounding resistance value is back to normal. The iPhone 6 Plus can enter the IOS system after booting, the display is normal, which means the failure has been fixed, the repairs are end!
